  • Page 4: Introduction

    1.0 INTRODUCTION The CPO-350 Variable Speed Cold Saw is designed to cut solids, tubes, flats and other profiles in grades of material that range from hot and cold rolled steel, annealed tool steels, stainless, aluminum, brass, copper, synthetics and extrusions. Cold sawing is a process similar to a milling process. In most cases, this, combined with the self centering vise feature and the variable speed drive, gives a finished cut that does not require any secondary machining or de-burring.

    On machines equipped with either a power vise or a power down feed, the air supply must also be disconnected and locked or tagged. Scotchman offers a lock-out switch for this machine as an option, if your plant is not equipped with lock-out capabilities. If you are interested in this option, REFER TO SECTION 7.7 or contact your local dealer or the factory.

    4.6 GUARD ADJUSTMENT-MANUAL MACHINES SEE FIGURE 4 ON THE FOLLOWING PAGE. FOR GUARD ADJUSTMENT PROCEDURES ON SAWS EQUIPPED WITH THE POWER DOWN FEED OPTION, REFER TO SECTION 7.2C. The proper adjustment of the blade guard on this machine is crucial to the operation of the machine and the safety of the operator.

  • Page 18: Coolant System

    4.7 COOLANT SYSTEM The coolant reservoir has a capacity of ten (10) gallons (37.8 liters). One gallon of coolant is shipped with the saw. For normal cutting, it should be mixed in a ratio of one part coolant to seven parts water. In conditions of heavier cutting, the ratio of water should be reduced to five parts.

  • Page 20: Cutting Oils & Lubricants

    5.2 CUTTING OILS AND LUBRICANTS SECTION 10.6 lists Scotchman’s parts numbers for cutting oils and lubricants. Using high quality lubricants and oils will greatly increase the life of this equipment. We recommend using only pure, synthetic, water soluble cutting oil for coolant.

  • Page 21: Scheduled Maintenance

    5.3 SCHEDULED MAINTENANCE A program of scheduled maintenance should be set up and documented according to your application and the frequency you use this machine. The following is a list of some important things that should be included in a scheduled maintenance program. 1.

    6.2 SAW CAPACITIES SEE FIGURE 7 BELOW. FIGURE 7 Figure 8 above is a chart showing the maximum capacities of this machine in various materials at the most common angles from 0 degrees to 90 degrees. PAGE 24...

  • Page 25: Selecting The Proper Blade & Cutting Speed

    6.3 SELECTING THE PROPER BLADE AND CUTTING SPEED In cold sawing, there is no such thing as a general purpose blade. To achieve the best results from your saw, proper blade selection is important. Each saw is shipped with a pitch (number of teeth) calculator, which will help to determine the proper blade for your application.

  • Page 26: Material Clamping

    6.4 MATERIAL CLAMPING All work pieces must be clamped securely in the vise. Any slippage of the material can result in broken or damaged blades. The material should be clamped so that the contact surface between the material and the blade is as small as possible. For this reason, when cutting flat stock material, we recommend standing it up and cutting it through the thinnest section, whenever possible.

  • Page 28: Miter Locking Device

    6.5 MITER LOCKING DEVICE SEE FIGURE 10 ON THE FOLLOWING PAGE. All models manufactured for domestic sales are equipped with a miter locking device which allows quick set-up for mitering at 45 degrees, left and right, and 90 degrees for straight cutting. A miter locking device is available as an option for models manufactured for international sales.

  • Page 30: Optional Equipment

    7.0 OPTIONAL EQUIPMENT 7.1 POWER VISE The power vise is an option that is normally ordered with the saw. A retrofit kit is available from your local dealer or the factory. The kit includes all parts required, plus complete installation instructions. The power vise allows automatic clamping of the material, which improves productivity and reduces operator fatigue.
  • Page 31 THE FOLLOWING ARE SET-UP AND MAINTENANCE INSTRUCTIONS FOR THE POWER VISE OPTION (RETROFIT OR FACTORY INSTALLED): 1. Before connecting the air supply to the saw, make sure that the filter/lubricating device (A) is full of oil. 2. Slide the shuttle valve (F) on the filter/lubricator device to the closed position. 3.

  • Page 36: Power Down Feed

    7.2 POWER DOWN FEED The power down feed option, used in conjunction with the power vise option, changes a manual saw into a semi-automatic saw. These options will increase productivity and reduce operator fatigue. The power down feed option cannot be retrofit to machines with serial number 11940491 and prior in the field. This option can be used on machines with or without the power vise option.
